Description/Abstract

The aim of the present study was to compare scapular kinematics whilst using the ‘silver standard’ scapular locator (SL) method and the acromion marker cluster (AMC) method during arm elevation and, for the first time, the lowering phase. Participants completed arm elevation and lowering in the sagittal plane to 5 discrete angles (0°, 30°, 60°, 90°, 120°). At each angle, concurrent SL and AMC recordings of scapular position were made using a Vicon MX T-series motion analysis system. There was no significant difference (p>0.05) between methods for scapular internal and upward rotation (max mean differences of -1.6°±5.7 and 2.2°±5.0) during both arm elevation and arm lowering. There was a significant difference (p=0.03) between methods for posterior tilt during both elevation and lowering phases (max mean difference = 5.7°±8.0). The AMC method for measuring scapular kinematics is comparable to the ‘silver standard’ SL method for internal rotation and upward rotation when measuring scapular kinematics during both arm elevation and lowering.
